Once upon a time, Peter Arnett, a well respected journalist, was fired for his story "Valley of Death." While this new revelation about the military's testing of Sarin on their own troops don't necessarily validate his story, it sure does give even more credibility to a fairly credible story.
Arnett retracted, and was still fired. Google on him and April Oliver for more details.
Into the Buzzsaw.
